ATTACHMENT FOR LOOIVIS.

Specification of Letters Patent.

Patented June 3, 1913.

Application filed July 27, 1912. Serial No. 711,802.

To all whom it may concern:

e it known that I, JULiUs BENZ, a citi- Zen of Switzerland, residing atBethlehem, in the county of Lehigh and State of Pennsylvania, haveinvented certain new and useful Improvements in Attachments for Looms,of which the following is a specification.

My invention relates to an improved attachment for looms, the object ofthe in Vention being to provide an attachment which is designed to beused in connection with the swells of an ordinary shuttle box, and whichwill prevent any possibility of the shuttle rebounding when it entersthe box.

Afurther object is to provide a device of this kind which can be quicklyattached to any ordinary loom and which will result in a vastly improvedproduct because it will preventany slack in the threads, and the goodswill be free of loops and be perfectly smooth.

It is a common defect with looms such as ordinarily made particularly inthe weaving of silk that the shuttles rebound from the shuttle boxes.This causes a slack in the silk or thread carried by the shuttle and theresult is a defect in the goods. My improved attachment is designed toprevent any rebound of the shuttle, thereby causing the thread or silkto be always taut and insuring a uniform product superior to the productof looms in general use.

A further object is to provide an attach ment of this character whichcan be attached to the shuttle box by any one of average intelligencenot requiring skilled labor, and

the invention consists in certain novel features of construction andcombinations and arrangements of parts as will be more fully hereinafterdescribed and pointed out in the claims.

In the accompanying drawings: Figure 1 is a fragmentary viewillustrating the lay of a loom and showing my improved attachment inconnection with the shuttle boxes. Fig. 2 is a view in elevation on anenlarged scale illustrating my improved device in operative relationshipto a shuttle box swell. Fig. 3 is a view in section on the line 3-3 ofFig. 2. Fig. 4 is a view in elevation at right angles to Fig. 2. Fig. 5is a view in section through the cushioned head of the device. vationillustrating Fig. 6 is a view in elea modification. Fig. 7

is a view at right angles to Fig. 6 showing the device in elevation andpartly in section. Fig. 8 is a view in section on the line 88 of Fig. 6.Figs. 9 and 10 are views in elevation at right angles to each otherillustrating another modification, and Fig. 11 is a view in sectionthrough the head of the device shown in Figs. 9 and 10.

1 represents the lay of a loom having the ordinary shuttle race 2 andthe ordinary shuttle boxes 3 at the ends of the race. These shuttleboxes 3 are equipped with swells 4 of any improved construction, andthese swells have a hinged mounting at one end as shown at 5, and arenormally held in position to be engaged by the shuttle as is common withdevices of this type in use. I would therefore hax e it understood thatmy invention is not limited to any particular construct-ion of shuttlebox or swell but is adapted to be used with any, and without modifyingthe construction of the box or swell in the slightest. These swells haveordinarily been equipped serve to retard the movement of the shuttle,but they are not suflicient to prevent the shuttle from rebounding.

My improved attachment is designed to prevent any possibility of therebound of the shuttle, and I have illustrated three different forms ofmy improved device.

With reference to the construction shown in Figs. 1, 2, 3, 4, and 5, 6represents a base plate which is adapted to be secured to the lay byscrews 7. This base plate is provided with a perforated post 8 to whichan arm 9 is pivotally connected by means of a rivet 10. On the free endof this arm 9, a cylin drical head 11 is formed, and in this cylindricalhead 11, a block 12 of rubber or other elastic material is positioned.This rubber block 12 bears directly against the swell 4;, and is heldagainst the same by means of a screw 13. This screw 13 is positionedthrough a perforated tongue 14 integral with the arm 9 and having itsenlarged head bearing against the outer face of said tongue, so that thepressure of the cushion block 1.2 against the swell may be regulated toexactly suit conditions. When the shuttle moves into the box, the rubberblock 12 will elastically resist the movement of the swell to such anextent that the shuttle will be sufliciently bound within the box toprevent any possibility of rebounding. The screw 13 is illustrated asscrewed into the box 8 and by with springs which.

turning this screw, the tension of the elastic block may be regulated.Such a device will last for a long time, but if the block loses itselasticity, it can be readily replaced.

In the modification illustrated in Figs. 6, 7, and 8, a somewhatdifferent design of base 15 is employed. The screw 13 engages thethreads in an opening 16 in the base 15 as well as being screwed intothe lay. Such a structure gives a more rigid support to the arm.

In the modification illustrated in Figs. 9, 10, and 11, a V'shaped baseplate 17 is employed which is provided with an enlargement 18 having ascrew-threaded rod 19 fixed therein. This rod 19 projects through anopening in an arm 20 corresponding to arm 9, and nuts 21 are provided onthe rod 19 at opposite sides of arm 20 so as to lock the arm at variousadjustments. This arm 20 has a head 22 fixed in its outer end and thishead 22 is recessed to accommodate the cushion block 12 as aboveexplained.

It will thus be seen may be made in various forms, but in any event willbe provided with means for adjusting the pressure of the elastic cushionagainst the swell, so given just the necessary pressure to preventanypossibility of the shuttle rebounding.

The attachments may be sold to the trade and used in connection with anyordinary loom, and various other slight changes might be made in thegeneral form and arrangement of parts described without departing frommy invention, and hence I do not limit myself to the precise details setforth, but consider myself at liberty to make such changes andalterations as fairly fall within the spirit and scope of the appendedclaims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. An attachment of the character described, comprising a support, ashuttle swell engaging member projecting at one end beyond the support,means for adjusting said member toward and away from the Copies of thispatent may be that my attachment that the swell may be support, and acushioning device on the free end of said member adapted to bepositioned against the swell of a shuttle box, substantially asdescribed.

2. An attachment of the character described, comprising a support, anarm ad justable on said support, said arm having a hollow head at itsfree end, an elastic cushion in said hollow head adapted to bepositioned against the swell of a shuttle box, and means for adjustingthe arm toward and away from the support, substantially as described.

3. An attachment of the character described, comprising a support, anarm adjustable on said support, said arm having a hollow head at itsfree end, an elastic cushion in said hollow head adapted to bepositioned against the swell of a shuttle box, a screw engaging the armand constructed to adjust the same toward and away from the support,substantially as described.

4:. An attachment of the character described, comprising a base, a poston the base, an arm pivotally connected to the post, a cushion blocksupported in the free end of the arm, a perforated tongue on the armbetween its ends, and a headed screw projected through said tongue andadapted to adjust the arm toward and away from the base, substantiallyas described.

5. In a loom, the combination with a lay, shuttle boxes on the lay, andmovable swells in the shuttle boxes, of swell engaging devicescomprising base plates secured to the lay, arms pivotally connected tothe base plates, cushion blocks in the free ends ofjthe arms, and screwsengaging said arms and screwed into the boxes, whereby the cushionblocks are adjusted toward and away from the swells, substantially asdescribed.

In testimony whereof I have signed my name to this specification in'thepresence of two subscribing witnesses.
